- Q:Why can aluminium hydroxide not be used to make refractory material?
- Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
- Q:How to divide the fire resistant level of construction thermal insulation materials?
- Combining three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division. And it is mainly determined in accordance with the national standard GB8624 Building materials combustion levels.
- Q:What brands are the best in the A-level refractory materials?
- This is two descriptions, glass wool refers to the texture of insulation materials, and A-lever refers to the combustion performance of fireproof materials. Generally the glass wool can achieve A-level combustion performance, unless you have add too many other combustible materials to it.
- Q:How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.
- Q:Are there any differences between insulation and refractory materials ?
- Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc.
- Q:How long is the fire-fighting time of A class fire resisting window?
- Duration of fire resistance of fire resisting window: A class window is not less than 1.2 hours; B class window is not less than 0.9 hours and C class window is not less than 0.6 hours. Technical Requirements: 1materials and accessories (1) window frame structure adopts stell framework and wooden framework that have a certain strength to ensure integrity and stability. (2) steel framework and batten can choose galvanized steel plate or stainless steel The selection criteria meet requirements of GB12955 steel fire door general technical conditions in the provisions of article 5.1. The selection criteria of wooden framework and batten meet requirements of GB14101 wooden fire door general technical conditions in the provisions of article 5.1.1. Filling material of steel and wooden framework shouldn't adopt non-combustibility material. (5) fire-fighting glass can adopt testing-qualified product that don't influence fire resistance performance of fire resisting window. Light transmittance of glass is not less than 75% of the same layer common plate glass. (6) Sealing material between framework and fire-fighting glass should adopt Flame retardant material which can serve as fire-fighting and smoke-resistant when encounter fire disaster. (7) hardware fitting should accessories product that is tested to be qualified. 二. installation requirement: 1. When Party A takes over goods, he should check numbers, specification, grades and whether Accessories are Conformed and complete according to contract.
- Q:Is aluminium oxide refractory material?
- Calcination aluminium oxide is refractory material of fine performance made from pure aluminium oxide through high-temperature calcination. It can be made into coarse-grained material, fine-grained material, fine powder and micro powder, which can be made into pure jade burnt products. For example, corundum brick, lightweight corundum bricks. It can also be made into a variety of unburning products together with other materials, such as carbonaceous materials. For example, aluminum carbon and aluminium zirconium carbonaceous materials. As for the production of unshaped refractory material, there are more species. It can be corundum, rubing grain, corundum spinel and can also be added into other materials to improve specific performance. It isn't limited to high-alumina castable refractory and it can be castable refractory, ramming?mass, impressionable plastic material, gunning mix and refractory mortar.
- Q:How to solve the shell, the crack problem of refractory material in the process of forming.
- Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
